Abstract
A machining operation generating unit analyzes a program in accordance with a machining program stored in the storage unit and causes the machine tool to perform a normal machining operation. A chip removal operation generating unit outputs an instruction for rotating a main shaft in the reverse direction to the interpolation unit after a cutting machining performed by the machine tool ends. The chip removal operation generating unit rotates the main shaft in the reverse direction for a predetermined time.
Claims4
A control device for an industrial machine that rotates a tool to cut a workpiece, the control device comprising:
- one or more processors that execute computer executable instructions stored in a memory,
- wherein the execution of the computer executable instructions configures the one or more processors of the control device to:
- select a time of a reverse rotation of the tool in accordance with material of the tool and a material of the workpiece;
- monitor a position of the tool;
- generate a reverse rotation instruction to start reverse rotation at a predetermined position of the monitored position for the tool;
- change a rotation direction of the tool in accordance with the reverse rotation instruction at an end of the tool cutting the workpiece;
- rotate the tool in the reverse direction after the tool cuts the workpiece;
- and
- stop the reverse rotation of the tool at the selected time for the rotation of the tool
- control the industrial machine in accordance with a machining program and cause the industrial machine to perform an operation in accordance with the machining program;
- and
- perform standby for the operation in accordance with the machining program while the reverse rotation continues.
A chip removal method for an industrial machine that rotates a tool to cut a workpiece, the chip removal method comprising:
- monitoring a position of the tool;
- generating a reverse rotation instruction to start reverse rotation at a predetermined position of the monitored position of the tool, wherein the reverse rotation instruction includes changing a rotation direction of the tool at an end of the tool cutting the workpiece;
- rotating the tool in a reverse direction in accordance with the reverse rotation instruction;
- and
- stopping the reverse rotation of the tool at a predetermined time selected in accordance with a material of the tool and a material of the workpiece
- controlling the industrial machine in accordance with a machining program and cause the industrial machine to perform an operation in accordance with the machining program;
- and
- performing standby for the operation in accordance with the machining program while the reverse rotation continues.
